Knp Rad Domain Event
A lightweight domain event pattern implementation for Doctrine2.
Official maintainers:
Installation
With composer :
$ composer require knplabs/rad-domain-event
If you are using Symfony you can update your app/AppKernel.php file:
public function registerBundles()
{
$bundles = array(
// bundles here ...
new Knp\Rad\DomainEvent\Bundle\DomainEventBundle();
);
}
Usage
Setup your entity
First, make sure your entity implements the Provider interface and uses the ProviderTrait.
use Knp\Rad\DomainEvent;
class MyEntity implements DomainEvent\Provider
{
use DomainEvent\ProviderTrait;
}
Raise event
Trigger any event from your entity, through the raise method. It will be turned into a Knp\Rad\DomainEvent\Event object and dispatched once your entity has been flushed.
use Knp\Rad\DomainEvent;
class MyEntity implements DomainEvent\Provider
{
// ...
public function myFunction($arg) {
// your function behavior
$this->raise('myEventName', ['anyKey' => $anyValue]);
}
}
Listen to this event
use Knp\Rad\DomainEvent\Event;
class MyListener
{
public function onMyEventName(Event $event) {
// your function behavior
}
}
Then, of course, register your listener.
app.event_listener.my_event_listener:
class: App\EventListener\MyEventListener
